In contrast, zymogenous bacteria need easily oxidizable organic materials for growth. … Thus, this summarizes the difference between autochthonous and zymogenous bacteria. A good perceptive view of microbial systems in the soil is an important prerequisite to understanding the impact of soil dynamics on biological control. During the first 14 d, the total amount of the aerobic and anaerobic, cellulose-degrading microorganisms increased significantly. “Classification of Soil Microorganisms Based on Growth Properties: a Critical View of Some Commonly Used Terms.” Research Gate, 2004. Microorganism plays very important role in agriculture because the soil microbes (bacteria and fungi) are essential for decomposing organic matter and recycling old plant material. In contrast, zymogenous bacteria need easily oxidizable organic materials for growth. Once high energy-containing nutrients are added, they show a rapid growth. Autochthonous bacterial population is uniform and constant in soil, since their nutrition is derived from native soil organic matter. “Caulobacter crescentus” (Public Domain) via Commons Wikimedia But, zymogenous bacteria need external energy resources or easily oxidizable organic substrates for their growth. Boheme, Livia. Therefore, zymogenous bacterial population fluctuates greatly unlike autochthonous bacteria in response to the availability of nutrients. Autochthonous bacteria are uniformly spread in soil, and their population does not fluctuate. 1.
